Question

I want to make Insert SQL Statement in Delphi using BDE Paradox which is

value_a := 0,123;
value_b := 0,234;
value_c := 0,345;
insert into mst_value values (value_a, value_b, value_c);

it shows the error like ‘invalid SQL parameter’ after debugging, it shows that the sql complete syntax like

insert into mst_value values (0,123, 0,234, 0,345) 

which is supposed to be dot but comma in the decimal, so I format it using formatfloat('#.###, value_a), …` it still using comma, after change the regional setting on Control Panel to English, the SQL parameter is correct, this is because the currency or number format there is just like 123,123,123.00, so, how can I format the decimal number but from another country e.g Indonesia with the format like 123,123,123,123.00 not 123.123.123,00. thanks before…

Try in this way, before calling the formatFloat function, you
can set appropriate value for Delphi’s variable ThousandsSeparator and DecimalSeparator :

FormatFloat( "$##.000", value_a );
